The term THEY MAY BE NOBLE can be solved by the five letter word GASES. Gases are a state of matter that is composed of particles that are spread out and have no definite shape or volume. They are made up of molecules that are in constant motion and can move freely through the space they occupy. Gases are often used in many industries, such as the production of energy, food processing, and chemical manufacturing. Gases can also be found naturally in the atmosphere, such as oxygen, nitrogen, and carbon dioxide.
